AudioDoc vs Google Flow Music (formerly Riffusion)

AudioDoc turns documents and pasted text into listenable audio in your browser. Upload a PDF, EPUB, or markdown file, or drop raw text into the TTS studio, and hear it read by natural narrators. There is no account requirement, no subscription, and no credit card gate to start.

The document library streams long files chapter by chapter as audio is generated, so you are not waiting on a full book conversion before playback begins. A separate TTS studio handles quick paste-and-listen jobs with downloadable clips and no watermarks.

It fits commuters who want articles read aloud, students reviewing coursework, writers proofreading drafts by ear, and anyone who needs hands-free or accessibility-friendly access to written material. Guest sessions last 24 hours; a free registered account keeps your library and listening progress beyond that window.

Google Flow Music lets you create full-length songs, remix tracks, and publish music through a conversational studio built on Google's Lyria 3.5 model. riffusion.com now redirects to flowmusic.app, where you chat with Producer like you are in a session, iterate on vocals and arrangement, and export finished tracks.

Unlike one-shot music generators that spit out a clip and stop, Flow Music focuses on iterative editing. Replace and Extend let you swap specific sections or continue a song past its endpoint without regenerating the whole track. You can also direct Veo-powered music videos, split stems, apply audio effects, and vibe-code custom instruments or mini apps inside Spaces.

The free tier includes daily top-up credits and two concurrent generations with no credit card required. Paid plans raise monthly credits, concurrent generation limits, and add member perks. Google acquired the Riffusion team in 2026 and folded the product into Google Labs alongside Lyria and Veo.
